Okay, here's the info from the 1080 file:

bitrate: 17669 kb/s
Stream #0.0[0x31]: Video: mpeg2video (Main), yuv420p, 1920x1080 [PAR
1:1 DAR 16:9], 16673 kb/s, 36.17 fps, 29.97 tbr, 90k tbn, 59.94 tbc
Stream #0.1[0x33](eng): Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s
Stream #0.2[0x34](eng): Audio: ac3, 48000 Hz, stereo, s16, 128 kb/s
Stream #0.3[0x111]: Data: TVG1 / 0x31475654
Stream #0.4[0x110]: Audio: mp1, 0 channels, s16

And the 720 file:

bitrate: 11208 kb/s
Stream #0.0[0x31]: Video: mpeg2video (Main), yuv420p, 1280x720 [PAR
1:1 DAR 16:9], 65000 kb/s, 59.96 fps, 59.94 tbr, 90k tbn, 119.88 tbc
Stream #0.1[0x34](eng): Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s

As I said, I'm a noob with ffmpeg...is this a start?

-b 11208 -aspect 16:9 -vcodec rawvideo
